There is another aspect: When a sociopath gets into a management position, that person presents one face to those above them and a totally different face to those below them. I know one such person who drove his employees much like that described in the article. He destroyed a whole department by his actions before top management got rid of him. (The only reason top management took action was that he was forcing some of the earliest employees to quit - those that were personally known by top management and could communicate around the chain of command.)

Any company that gets to the size of Amazon will have sociopaths and psychopaths in their management structure. Jeff Bezo may not realize that such can happen and may have structured the company structure to be very efficient - assuming that such people won't infect his company.
